Found a way to fix my DX50's problem with static. I just cut a 1cm square of aluminium foil, placed it on the pin under the battery cover and replaced the cover. Problem has gone away, and the sound has improved as well ( mainly noticed the treble previously was a bit out of control and sharp, now its perfect). So I guess I'm back to being a fairly happy DX50 user, but still a bit annoyed that mine came with a defective back cover grounding surface.
